Instructions

To prepare the brownies, combine the granulated sugar, cocoa, butter, eggs, flour, vanilla, and pecans in a medium bowl; stir until just blended. Pour the batter into the prepared pan and bake 15 to 17 minutes, until a wooden pick inserted 1 inch from the edge comes out clean. It will not be done in the center at this point.

Arrange the marshmallows on top of the brownies, about 1/2 inch apart, and bake 5 minutes. Remove from the oven. Using the back of a spoon, press marshmallows to spread slightly covering the surface of the brownies. Cool in the pan on a wire rack.

To prepare the frosting, combine the butter, evaporated milk, vanilla, confectioners’ sugar, and cocoa in a medium saucepan. Cook over medium-low heat, until smooth, 4 to 5 minutes, stirring frequently. Remove from the heat and cool. Spread over the cooled brownies and cut into squares.
